de Vries Isolatietechniek Reviews 

De Vries Isolatie was supposed to install underfloor insulation at our home. They convinced us to go ahead with it through a very convincing sales pitch.

After four months, an appointment was finally scheduled. However, on the first two occasions, De Vries Isolatie simply failed to show up. And this sums up the entire process: absolutely no communication.

When I contacted them myself, I received an apology and was told: “I’ll look into it for you and get back to you tomorrow.” I never heard from them again.

After another month of poor communication, two friendly contractors from an external company finally came to install the insulation. Within five minutes, however, they concluded that it was not possible to install it in our crawl space due to issues that should also have been clearly visible to the original salesperson.

In other words, because they wanted to make the sale, they failed to properly assess the situation and could have saved us months of hassle.

Conclusion: absolutely appalling communication.

Just had de vries isolatie come and finish the dak isolatie. Eventhough they could not finish in one day, the came first thing the next day to finish -
After first confirming by email. Clear explanations and polite and careful personnel! Would recommend

Exceptional service from Nazar and Bodhan!
"I recently had my floor insulation installed by De Vries Isolatietechniek, and I cannot recommend Nazar and Bodan highly enough. They are professional, friendly, and very modest young men.
Not only did they carry out the physically demanding work with great enthusiasm, but they also provided excellent advice regarding the ventilation of my home. It’s clear they take great pride in what they do. We made sure to keep them fueled with coffee and cookies, which was the least we could do for the hard work they delivered.
Much respect for these young professionals. If you get Nazar and Bodan for your insulation job, you are in great hands!"

We had the crawl space floor insulated with PIF insulation, and they did a great job quickly.
The men were very friendly, and I'm very satisfied.

Excellent! First, a very nice consultant showed up and explained what needed to be done, what was not, and what was feasible. Once we accepted the offer, they scheduled an appointment very quickly. Then the impressive part starts. The guys really know what efficiency means! They completed the project in no time and left the house tidy. An extra point for friendliness. Plus, they do speak English. Thank you, de Vries Isolatietechniek-Team!
